I totally hear you! I was just about to figure out how to post about this, but your post sums it up so nicely! I was banded on Thursday, and have a tightness in my chest and the 'baseball' feeling, although without the burping action. Kind of feels like a burp stuck? Anyway, I literally feel your pain, I am hoping it goes away with time, otherwise I have just made a REALLY bad decision getting banded! Any more advice would be greatly appreciated, hope you are feeling better soon!
